 compatibility

- Added curl installation in Debian slim runner stage
- curl is required for healthcheck in docker-compose.yml
- curl is pre-installed in node:20-slim base image was incorrect assumption
- Healthcheck uses: curl -f http://localhost:3000/
- Cleaned up apt cache to keep image size minimal
